I don't think we shipped 'clushutdown' on RHCS4, actually.  It might be
something we could do in the future.

Anyway, in U4, the service lock will be global, so you only have to run
'clusvcadm -l' on one node.

Running 'clusvcadm -l' will prevent all 'start' failover service
transitions.  Basically, after running it, the cluster will only 'stop'
services.  You only need to do this if you're trying to shut down the
whole cluster for some reason.  Normally, stopping rgmanager will cause
services to migrate to other nodes; locking rgmanager prevents this.

After locking rgmanager, you can just run 'service rgmanager stop' on
each node to cleanly shut down all running failover services.
